[Foucault-L] Foucault - Chomsky on Human Nature

I have recently read two different versions of the opening words by Fons Elders:

a) in english (the New Press with a foreword by Rajchman)

Elders compares the two speakers to “tunnellers through a mountain working at opposite sides of the same mountain with different tools, without even knowing if (!!) they are working in each other’s direction”.
